Chatwoot adds WhatsApp BSUID support ahead of Meta's phone number privacy rollout
Chatwoot is a mature open-source customer support platform actively investing across three parallel tracks: WhatsApp-first CX features (BSUIDs, template management, setup UX), voice calling infrastructure (dedicated dashboard, granular recording and transcription controls), and Captain AI (audience and schedule settings). The shipping cadence is strong — multiple substantial releases per month — and the product has moved well past basic multi-channel inbox to a full-featured support platform.
Fonoster 0.22.x fixes audio playback lifecycle and process crash on hangup
Two back-to-back patches address audio SDK correctness: v0.22.13 fixes playStream to resolve only after playback completes (previously it could resolve prematurely), and v0.22.14 catches unhandled promise rejections on call hangup that would crash the Node.js process. Both touch the call/audio lifecycle, which is the core of Fonoster's programmable voice SDK.
Chatwoot is a mature open-source customer support platform actively investing across three parallel tracks: WhatsApp-first CX features (BSUIDs, template management, setup UX), voice calling infrastructure (dedicated dashboard, granular recording and transcription controls), and Captain AI (audience and schedule settings). The shipping cadence is strong — multiple substantial releases per month — and the product has moved well past basic multi-channel inbox to a full-featured support platform.
WhatsApp is the clearest strategic thread: Chatwoot is building deeper platform integration than any other open-source support tool, and the BSUID support is a forward bet on Meta's privacy-preserving username rollout that most commercial competitors haven't addressed yet. Voice calling infrastructure got a meaningful overhaul in August and September, suggesting it's being treated as a first-class channel rather than a bolt-on. Captain AI is gaining routing intelligence through audience and schedule controls, pointing toward conditional agent orchestration rather than a simple on/off toggle.
Captain AI will get conditional escalation logic next — the existing audience and schedule controls are clearly laying groundwork for rules that route conversations between AI and human agents based on content signals, not just timing.

Both touch the call/audio lifecycle, which is the core of Fonoster's programmable voice SDK.
Fonoster is in active maintenance of the 0.22.x line, addressing stability issues in the audio primitives. The fixes are focused correctness patches — no new feature surface visible in these entries.
A feature release for 0.23.0 is likely once this patch cycle settles; the narrow scope of recent fixes suggests the core SDK is maturing.
